Outdated connector components for IS-KM on APIM documentation

[vfraga]

It seems the components shared in the Step 4 on Set up WSO2 Identity Server as a Key Manager [1] doesn't match what's available on the latest update level for APIM 4.0.0. This is an issue as some fixes applied to these extension components won't get deployed to the Identity Server if the enduser downloads them from the official docs.

The downloaded zip file contains components:
wso2is.key.manager.core-1.2.10.jar
wso2is.notification.event.handlers_1.2.10.8.jar
keymanager-operations.war (1.2.10.5-SNAPSHOT)

However, the latest update level contains the below:
wso2is.key.manager.core-1.2.10.17.jar
wso2is.notification.event.handlers_1.2.10.8.jar
keymanager-operations.war (1.2.10.20)

IS-side Git issue: wso2/product-is#20153
